TST伸縮縫不僅適用于溫差變化不大南方地區(qū),對于溫差較大的我國西北,東北等地也可以使用。在全國范圍內(nèi)都可以正常使用。由于TST的高溫粘附特性,在施工時可與現(xiàn)有路面牢固粘結(jié)變快,常溫不粘,冷卻后也不會被帶走。TST伸縮縫使用壽命長,如果嚴(yán)格按照生產(chǎn)工藝安裝的無縫粘接料,它的使用壽命是一般改性瀝青路面的兩倍左右。并且有很好的舒適性,能充分吸收各種大型車輛振動沖擊,車輛駛過舒適平穩(wěn)。
TST expansion joint is not only suitable for the southern region with little temperature difference, but also can be used in the northwest and northeast of China with large temperature difference. It can be used normally nationwide. Due to the high temperature adhesion characteristics of TST, it can be firmly bonded with the existing road surface during construction and become faster. It is not sticky at normal temperature and will not be taken away after cooling. TST expansion joint has a long service life. If the seamless bonding material is instalLED in strict accordance with the production process, its service life is about two times that of the general modified asphalt pavement. And has a good comfort, can fully absorb the vibration and impact of a variety of large vehicles, vehicle passing comfortable and stable.
TST伸縮縫安裝注意事項:
1.伸縮縫在安裝前一旦碰撞變形,很難修復(fù)為合格產(chǎn)品,所以在安裝的全過程中,一定要采取措施保護,嚴(yán)禁任何車輛通過。
2.安裝伸縮縫要求嚴(yán)格,一定要精心操作。由于現(xiàn)場不易調(diào)整,所以成品檢查一定要認(rèn)真、仔細(xì)。不合格不可運至現(xiàn)場。
3.伸縮縫安裝前,要與設(shè)計圖和現(xiàn)場核對位置、尺寸無誤后,再穩(wěn)放入預(yù)留槽。
4.橋上各接縫處縫隙一定要用聚苯乙烯泡沫板塞嚴(yán),防止?jié)沧⒈Wo帶混凝土?xí)r灌入,使縫失效。同時,也不可將裝置內(nèi)灌進混凝土,以免更換V形象膠帶時受阻。
5.伸縮縫保護帶混凝土澆筑后,前七日一定要及時灑水養(yǎng)護,以利強度增長和防止裂縫出現(xiàn)。
1. once the expansion joint is deformed by collision before installation, it is difficult to repair it as a qualified product, so in the whole process of installation, we must take measures to protect it, and it is strictly prohibited for any vehicle to pass through.
2. The installation of expansion joints is strictly required and must be carefully operated. Because the site is not easy to adjust, so the inspection of finished products must be careful and careful. Disqualified can not be transported to the site.
3. Before the installation of the expansion joint, it is necessary to check the position and size with the design drawing and the site, and then steadily put it into the reserved slot.
4. The gap at the joint of the bridge must be blocked with polystyrene foam board to prevent pouring into the protective belt concrete, so that the joint failure. At the same time, the device can not be filLED with concrete, in order to avoid the replacement of V image tape blocked.
5. after the concrete pouring of the expansion joint protection belt, the first seven days must be timely sprinkling maintenance, in order to increase the strength and prevent cracks.
TST伸縮縫原理與特點
所謂“彈性接縫”就是一種粘彈性結(jié)合材料來做的接縫,使接縫產(chǎn)生一定的彈塑變形來適應(yīng)結(jié)構(gòu)的變形。其性能特點如下:
1)TST伸縮縫是一種特制的高粘彈塑性材料,常溫下呈彈塑態(tài),高溫熔溶后可熱灌人碎石中,成型后如同瀝青砼狀,能承受車輛荷載,又有彈性,可代替小伸縮縫的功能。
2)構(gòu)造簡單,TST碎石直接鋪在橋梁接縫處,與前后的橋面鋪裝形成連續(xù)體,橋面平整無縫。這種彈性接縫能吸收各方面的變形和振動,行車平穩(wěn)、舒適、無噪音、振動。
3)施工方便快捷,鋪裝冷卻后,即可開放交通。當(dāng)伸縮縫需要進行更換時,可半邊施工。對交通繁忙路段不中斷交通。
4)接縫和橋面鋪裝聯(lián)成一體,密封防水性好,且造價低、耐用。
TST無縫伸縮縫適用一年中的各個時期,通常在零下-40℃時橋面不會變脆,在夏季高溫達80℃時不會流動。
1)TST expansion joint is a kind of special high viscoelastic plastic material, elastic plastic state at room temperature, high temperature melt can be hot poured into the gravel, after forming like asphalt concrete, can bear the load of vehicles, and elastic, can replace the function of small expansion joint.
2) Simple structure, TST gravel is directly laid at the bridge joints, forming a continuum with the front and rear deck pavement, and the bridge deck is smooth and seamless. This elastic joint can absorb all aspects of deformation and vibration, driving smooth, comfortable, no noise, vibration.
3) The construction is convenient and fast. After the pavement is cooLED, the traffic can be opened. When the expansion joint needs to be replaced, half construction can be carried out. Traffic will not be interrupted on the busy road sections.
4) joint and bridge deck pavement together, sealing water resistance is good, and low cost, durable.
TST seamless expansion joint is suitable for all periods of the year, usually at minus 40 degrees Celsius when the bridge deck will not become brittle, in summer high temperature up to 80 degrees Celsius will not flow.
